This building is an existing 5 story office building with a plan size of about 220 feet by 75 feet. The new units are to replace existing units. The roof framing is comprised of metal decking, wide flange joists, and wide flange girders. One new unit is around 1150 lbs and the other is about 1850 lbs and each will use new adapter curbs to fit up with existing conditions. Included in the scope is the lateral anchorage of each unit and analysis of existing support framing. Each new unit is less than 20 feet in length.

'w °`" Controller C08208 The controller (see Fig. 60) includes a controller housing, Fig. 60 - Controller Assembly a printed circuit board, and a clear plastic cover. The controller can be connected to one or two compatible duct I smoke sensors. The clear plastic cover is secured to the °�� . housing with a single captive screw for easy access to the ,1 .10111"t �� wiring terminals. The controller has three LEDs (for '' Power, Trouble and Alarm) and a manual test/reset button '` _ (on the cover face).

Cover gasket inspections without having to disassemble the sensor. The ' cover attaches to the sensor housing using four captive screws and forms an airtight chamber around the sensing r %v � l°r op../ r CQe electronics. Each sensor includes a harness with an RJ45 r,,,,, -. terminal for connecting to the controller. Each sensor has ' r (ordered four LEDs (for Power, Trouble, Alarm and Dirty) and a oetTA manual test/reset button (on the left-side of the housing). \ r co..re •. Air is introduced to the duct smoke detector sensor's sensing chamber through a sampling tube that extends into the HVAC duct and is directed back into the ventilation system through a (shorter) exhaust tube. The difference in air pressure between the two tubes pulls the sampled air "" u °"w it through the sensing chamber. When a sufficient amount of ;<h smoke is detected in the sensing chamber, the sensor ° signals an alarm state and the controller automatically Alarm Power Trouble at1 takes the appropriate action to shut down fans and blowers, change over air handling systems, notify the fire C08209 Fig. 61 - Smoke Detector Sensor alarm control panel, etc. 38 The sensor uses a process called differential sensing to Return Air Detector module (shipping position shown)` prevent gradual environmental changes from triggering false alarms.

The sampling tube *RA detector must be moved from shipping pp' g position to operating position by installer inlet extends through the side plate of the fan housing C07307 (into a high pressure area). The controller is located on a Fig. 63 - Typical Return Air Detector Location o bracket to the right of the return filter, accessed through U the lift -off filter panel. '— Return Air with Economizer — The sampling tube is 4 inserted through the side plates of the economizer housing, placing it across the return air opening on the unit basepan. See Fig. 64. The holes in the sampling tube �� face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is '� �„„ mounted on a bracket high on the partition between return (: ;� , filter and controller location.

This device may be a separate humidistat ' OD control (contact closes on rise in space RH above control o setpoint) or a combination thermostat - humidistat control " z CID device such as Carrier's EDGE Pro Thermidistat with �� C11 o CE isolated contact set for dehumidification control. The ° FF o� OD humidistat is normally used in applications where a OD temperature control is already provided (units with % RELATIVE NINNRY PermierLink'" control). To connect the Carrier humidistat (HI38MG029): C09295 1. Route the humidistat 2- conductor cable (field -sup- Fig. 67 - Accessory Field- Installed Humidistat plied) through the hole provided in the unit corner post. 2. Feed wires through the raceway build into the corner 9 post (see Fig. 29) to the 24 -v barrier located on the left side of the control box. The raceway provides the v UL- required clearance between high- voltage and low - voltage wiring. I I F 3. Use wire nuts to connect humidistat cable to two IL F PINK leads in the low — voltage wiring as shown in actual temp Fig. 69. To connect the Thermidistat device (33CS2PPRH -01): 59 outside temp 1.
